Monster skill

Monster skills are skills used by monsters or NPCs in Guild Wars that are unique to those monsters. They cannot be learned (through Skill Trainers) or captured (through a signet) by players. Also, Mesmers can't "steal" them with spell theft or mimicking skills like Arcane Thievery. However, Inspired/Revealed Enchantment and Inspired/Revealed Hex will remove the hex/enchantment and provide an energy bonus, but, being unable to copy the skill, they will recharge instantly.

(12 seconds.) A signal flare is fired into the air to summon siege fire from any nearby garrisons. Every 3 seconds, targets hit by the siege fire take 40 damage and are interrupted. Easily interrupted.

Dhuum deals 200 damage to a new target with each strike. Dhuum only strikes a foe once in this way and will stop this attack after the fourth strike or when no eligible targets are in the area of his last strike. Dhuum is untargetable during this attack.
